Improvement in car-axles



NITED STATES PATENT WILLARD WINSLOW, OF LOWVILLE, NEW YORK.

IM PRvi-:M ENT IN cAR-AxLEs.

Specification forming part of Letters Patent No. 190,175, dated May 1,1877 application led March 21, 1877.

To all whom it may concern;

Be it known that I, WILLARD WINsLow, of Lowville, Lewis county, NewYork, have invented Improvements in Divided Axles for Gars, of which thefollowing is the specication: l

The object of my invention is an improvement in that class of axleswhich are divided in the center, a section being attached' to eachwheel; and my improvement consists in dividing the box longitudinally,and providing it with external ribs, and making the axle with annulargrooves, with recesses adapted to receive a loose block, and withoiling-chan nels, arranged as hereafter described.

In the drawing, Figure 1 is a longitudinal section of sufficient of anaxle and coupling to show my improvement; and Fig. 2 is a transversesection on the line a: x, Fig. l.

A A are the two sections of a divided axle,

the ends of which butt together, as shown. Each section has two annulargrooves, c, forming two annular projections or collars, b, and ashoulder, c, and to that portion of the axle between the shoulders istitted a coupling-box, B. The coupling-box is divided longitudinally onthe line y y, Fig. 2, and each half ts nicely to the correspondingportion of the axle, as shown, and the two parts are clamped togetherand upon the axle by bolts e e, which may be provided with elasticwashers, to prevent thern from turning. coupling-box permits theindependent rotation ot' either section of the axle; but the internalannular projections t' of the box, which extend into the annular groovesall of the axle, electually prevent any endwise movement of eithersection, and maintain their relative position. In order to relieve thebox from strain resulting from the tendency of' the end of eithersection to move radiallyindependent of the other, coinciding recessesare formed in both ends, to receive a loose plug, n, which eft'ectuallysecures the desired result.

Thus applied, thel In order to eiect the rea-dy lubricating of 'thebearings, and especially at thepoint where most friction exists-that is,at the center of the box-an oil-channel, s, is formed in the end of eachsection, and extends to a radial channel, s,beyond the en d ot' the box.Th rough this channel an abundant supply of oil may at any time beapplied to the center bearing, from which it nds its way to all theother frictional points. Y'

In order` to reduce the Weight of the box, and at the same time securethe requisite strength, each section is formed with longitudinal ribs m,and transverse ribs n', arranged at suitable intervals.

It will be seen that, while this construction readily secures the twosections and retains them in position, it is extremely simple, and

is strong, and permits the sections to be easily connected or detached,and all the parts to be readily lubricated without any possibility ofdust or grit reaching the wearing-surface.

I claim- 1. The combination of the sections A A', their annular grooves,recesses, and channels s s', the box` B divided longitudinally, andadapted and applied to the axle and secured by transverse bolts, as setforth, and the pin n, fitting coinciding recesses in both sections, allas described.

2. The Mbox consisting of tbe sections d d', adapted to the axle, itsprojections and grooves, each section having longitudinal ribsnl andtransverse ribs n', as set forth.

In testimony whereof I have signed my name to this specitication in thepresence of two subscribing witnesses.

WILLARD WINSLOW.
